The coordinates of each point are defined by two dataframe columns and filled circles are used to represent each point. They take different approaches to resolving the main challenge in representing categorical data with a scatter plot, which is that all of the points belonging to one category would fall on the same position along the axis corresponding to the categorical variable. Can I not directly use the index for x-axis? This data captures the relationship between two variables related to an economy: Step 2: Create the DataFrame. ', density_kwds = None, hist_kwds = None, range_padding = 0.05, ** kwargs) [source] ¶ Draw a matrix of scatter plots. kind=’line’,x= ‘some_column’,y=’some_colum’,color=’somecolor’,ax=’someaxes’ Python3. color — Which accepts and array of hex codes corresponding sequential to each data series / column.
